如何使TextBox成为“密码框"?和使用MVVM时显示星星?

问题描述

如何在XAML中做到这一点?

How can I do this in XAML:

伪代码:

<TextBox Text="{Binding Password}" Type="Password"/>

，以便用户在输入密码时看到星号或点.

so that the user sees stars or dots when he is typing in the password.

我尝试了各种示例 PasswordChar 和 PasswordBox ，但无法使它们正常工作.

I've tried various examples which suggest PasswordChar and PasswordBox but can't get these to work.

例如我可以按照此处所示的方式进行操作:

e.g. I can do this as shown here:

<PasswordBox Grid.Column="1" Grid.Row="1"
    PasswordChar="*"/>

但是我当然想将Text属性绑定到我的ViewModel上，以便在单击按钮时可以将绑定的TextBox值发送给我(不适用于后面的代码)，我想这样做:

but I of course want to bind the Text property to my ViewModel so I can send the value the bound TextBox when the button is clicked (not working with code behind), I want to do this:

<TextBox Grid.Column="1" Grid.Row="0" 
    Text="{Binding Login}" 
    Style="{StaticResource FormTextBox}"/>
<PasswordBox Grid.Column="1" Grid.Row="1"
    Text="{Binding Password}" 
    PasswordChar="*"
    Style="{StaticResource FormTextBox}"/>

但是PasswordBox没有Text属性.

But PasswordBox doesn't have a Text property.

推荐答案

要在PasswordBox中获取或设置密码，请使用Password属性.如

To get or set the Password in a PasswordBox, use the Password property. Such as

string password = PasswordBox.Password;

据我所知，这不支持数据绑定，因此您必须在后面的代码中设置值，并进行相应的更新.

This doesn't support Databinding as far as I know, so you'd have to set the value in the codebehind, and update it accordingly.
